1981
from drowning shocked the world. a who's who of hollywood among the mourners at her funeral. to some friends, the tragedy didn't quite add up, because

dark water
,
sea water
.

>>cause of death
will be certified as accidental drowning.

>> reporter: right after her death, her lawyer tried to dampen speculation there had been some sort of foul play.

>>the facts are clear, they're uncontradicted. the important facts, and the rest, is just ghoulish nonsense.

love triangle
. a possible argument on-board the boat between the two men. and in a tell-all book published last year, the captain "the splendor," dennis davern said he saw

wagner
drowning." a statement from
robert wagner

wagner
family fully supports the sheriff's investigation. the family added they hope this isn't a case of someone trying to make a profit off the
30th anniversary
of
natalie wood
's drowning. there has been no reaction from
christopher walken
. david?
